Good versus Evil - II

This will significantly prolong the tournament; instead of 8 games, it will take around 20. Moreover, it will be difficult for the organizers to control the group stage in terms of timing, and it might drag on. Then, let's say, if the top players in the final group table are all "good" or, conversely, all "evil," what then? There might be a strong elimination right away, and they will mostly play as one faction, or do you plan to make a clear division, for example, by having the top 4 "evil" and 4 "good" players advance?

Two evil and two good players advance. Then, they compete in a knockout stage, playing against each other. Currently, there are 14 players; in the group stage, they need to play only 7 games (i.e., you need to play against each of the "good" players). If you take 1st or 2nd place in your group based on points, you play one more game; if you advance to the final, you play one more. In total, a maximum of 9 games. In case of a tie in points, you can flip a coin :)

You can do it differently – have 4 players advance from the group based on points, which means one more game (resulting in an additional 1/8). You can also play with a winners/losers playoff bracket, but again, these are all additional games. It doesn't really matter in that case.
Of course, in the final, it might happen that both villains advance – it doesn't matter; let them simply determine the strongest :)

ps: by the way, with 14 players, you can make it so that in the playoffs, only the last remaining race plays. And the final, for example, could again be played to 1/3/5...45 wins
